TO ALL WHOM IT MAY eonenim:

'Be it known that i, .SAMUEL LEWIS, of Brooklyn, in the'connty of Kings,and State of'New York, have invented a ncwvand improved Ice-Planer and I.do hei-eby'declare that-the following is afull, clear, and exactdescription thereof, reference being had to the accompanying drawings,and'te the lettersand figures of-rcfrenco marked thereon.

The object of this improvement is to obviate the many antlserionsdiihculties in'the treatment of thesurface' of ice which have heretoforebeen experienced bythosehavingchargo of skating-ponds erehgaged inthebusiness of cutting ice for'the market. I

'ItLis-a fact well known that the old ice p'lane'r had, in most cases,its operating-edge-sct with thabevelled side do'wnwardyand was attachedin other respects-somewhat after themannen of the carpenter's plane,with but poor .devicesor'nonefor, changing the angle of thekn iie or.varying the depth of its cut, In practical use, this primitive machinehas always exhibited a tendencyto ride over the inequalities it wasintended to remove,

while the imparting-0f a new and even surface to an entire pond wassimply an impossibility.

In the attempt to escape from a portion ofthese d iih cuities, a loadwasput upon the old machine, which was only so mnchextra'lahsr;uponfhorses, withso mnch more dangerof cracking or otherwiseinjuring the ice. Even in' the apparatus in which the-blade was set inthe rational manner-{the iihsence of other and indispensable devicesrendered the machine of little utility, and very-arduous to operate,since, owing to the old method'of attaching the knife, a-largequantity-of cut i s was drawn along with the machine, theolearance ofwhich was prevented by the beam to which said knife was attached..Moroovcr, in all the ice-planners heretofore made, to thehestofpetitioners knowledge and heliefltho knife ias'heen set at afalse-angle, and in such a manner new cause the adhesion of frozenmatter to the under side of the blade, increasing the-tendency to ride"before referred to.

Such was the status of the mechanical treatment of the'surface of"icewhen your petitioner became practically interested therein; andperceii'ing that the luxu-ryef'la fine surface to the skater and alucrative husiness to the manager could be secured only -by the greatimprovement of-the accessory impleinents, helost no time in devising andputting intopractical operation theiinprovements herewith submitted,which havegiven the pondwith which he is connected at the moment of. thepre'sentwriting the monopoly of skating. in the" metropolitan, districtof New York. v I I To enable others skilled in the art to make and userny invention I will proceed to describe its construction ando perationrFigure 1 is a vertical'longitndinal sectienof the machine in the line'ofm x, fig. 1.

-Figurefl is a vertical transverse section of the same, takon'dn theline yy, fig.'1.

Figure 3 is a front or faceview of a portion of the same.

Figure .4 is a view" of the under face of a portion of the knifepertaining to the same. 3

Figure 5 is an enlarged viewof'the ine'ahs by which-the knife isattached to-and sccurcd'in place.

The prineipahfeatures of this iinproved planor are, the knife 1 with itsflat side to the ice, its greater dipping ungle, and. its peculiarattaehinenfl-the. latter furnishing ,an unobstructed escape for the outice the bolts 2 .2, the braces 3 3, the vertical cutters 9 9, thebrake-or elesator 16, and the adjustablech'araterof all its workingparts. Q

'The frame, .of any-suitable timber or metal, is composed of the sides20 20, the behm'sg21, 22, 23,' and the top or flooring 24 and 27. Itslength is such as to span any incidental hollows in-the ice,therehy-tonding to restore to the whole pond its original plane suri'ace. The seat is made removable, to facilitate theadjustment of theknife, and for the convenience of transportation, The desired angle ofthe knife 1 results from the bend near the head of the-bolts 2 2, andthe inclination of the under face of the lower end of the braces thetaper washers 5 5 compensating said inclinatiom'and furnishing a faceparallel-with that of the binding-nuts 4 4. The-manner of attaching theknife is to run, the bolts 2 2 through the new ends of the braces. 3'3,'aiid run on tosaid bolts the taper washers and nutsi land 77; thebolts are then'in'sertedthrongh the beam, as shown, and the upper nuts'8 8 run on; 'the dipper ends of braces 3 3 are then-placed-a's shown infigs; 1 and 3,, the bolts 6 6 inserted and the nuts run on; the knife],is then put in place by passingthe'slots b ever't'he bolts 2 2; the dipor out of.the knife is determined upon, andfthe'nuts 8 8 placed"accordingly; the'nuts-.7 .7 and 6.6 are then screwed horno and finallythe taper washers 5 5 are properly placed, and the nuts 4 4 screwed downtill they bind the whole cntting-apparatus together, as seen in fig. -5.As will bc seen at a-glsnoe, the nuts 8 8
